IMPROVEMENT IN PRINTINGfPRESSES. r

Be it known that I, J., M. JONES, of Palmyra, in the county of Wayne, and 'State 0f New Ql'lf: have invented new anduseful Improvements in"l?rinting-Iresses; and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, whereinV I have set forth the natureand principles of my said improvements, by which my invention may bc distinguished from all others of a similar class, together with such parts as I claim, and desire i6 hlveclled to me by Letters Patent.

The present invention consistst n First, ina novel arrangement of parts for ,bringing the platen of the press up nearly to thc form, where, by means of an armor arms, made to interlock therewith, and to move in the proper direction, the i platen is thcn brought against the form and the impression given.

Second, in the combination Vwith the arm or ,arms above-,referred to, for moving the f plat'll ik ith@ impression from the form, so1 arranging a cam or cams, o'r its or their equivalcnt's,a s to then operate t-o dirson gagesaid arms from the Aplatenf and leaving it free to fall or to be moved away from the form, thus throwing oit the impression thereon.

' Third, in the combination, with the said cams for disengaging the impression-arms from the platen, ofa

lever or levers, for so holding such cams as to prevent the said arms from becoming engaged with the platen 4 v while the press is running, if so desired.

Fourth, in a novel manner of securing the chase to the bed of the press. Y

Fifth, inso arranging a lever, in connection with the franie or other equivalent part for carrying' the inkroller over the form, or the device or devices for operating such frame, that the'ink-rollor can be detained upon the ink-cylinder-when desired, for distributing the ink, or for any other purpose. i

Sixth,l in providing the frame carrying the platen with a box or receptaclefor the cards, tc., printed, to drop or fall into, in such manner as temperato alsoas-a counterbalance or weight to the platclh Seventh, in connecting with the frame carrying the"plateni a spring or springs, in such a manner as to facilitate the movement of the platen, as will be hereinafter described. i l

Having thusi n general terms, stated the principal features of the improvements embraced in the present invention, I will new proceed to explain the same in dtail, reference being had to the accompanying plate of drawings, in which- Figure 1 is a side elevation of a printing-press made according thereto,

Figure 2 a plan or top view of the same, and

Figures` 3 and 4 detail views, to be hereinafter referred to.-

Figures 5 and 6 are views ofi parts to be hereinafter-referred to. l

A, in the drawings, represents the supporting framework of the press, which consists of two parallel upright fram-es, B, of suitable form and construction therefor, joined and braced together in anyproper manner.

" C, ashaft, towhich a ily or balance-wheel, D, is securerLand through which the power necessary to drive *the press iste be transmitted.

This shaft G is horizontally arrangedto turn in bearings of one of the frames B, and at its inner end has secured to it a pinion-wheel, F, which engages with a large gear-wheel, G, keyed to a horizontal shaft,-H, above, that eiztends entirely across the framework A, turning in suitable bearings of each of its Vframes B, Upon eachend ofthe gear-wheel shaft H is lined a similar arm, I. These arms I,in bothcases, are encased by similar boxes, J, that are located upon the outside of the frames B, to vmoveY in4 a horizontal` direction, or nearly so, by their slotted ends, K, upon pins L, 'suitably fixed therefor in the said frames, their opposite ends,

` M, being continued by arm N, in each case, throughixcd guides or loops, O. I The arms N are extended toward the frantoi' the press, where the form P is located, and the platen Q arranged to operate, as will be presently explained, and at their outer ends have ahead or cap-piece; R.

Connected with each of these boxes J'is a bent spring, J2, suitably located to thi-bw or draw back theboxes after being moved 'by means of the arms I.

Within each of the boxes J is arranged a roller, S, for thetshaft-arms I, as their shaftis turned, to bear against, and thus to move the said boxes upon their guidelpins L, as and for purpose to be hereinafter stated. The form P is xcd to the chase T. This chase T is secured to the front of the bed U of the-press', in an upright position, by means of hooks, Y, fixed in the bedU, that grasp the lower edge, W, to the chase, andthe hook X, grasping the upper edge, Y. This upper hook X is ixed to one end of a lever, a, hung at its other end to' a fulcrum on the rear side of the bed U, with which lever c t is engaged the arm b to a horizontal shaft, c, (turningin suitable bearingsof the framework,) that, at its outer end, is provided with a proper lever or handle, d, for turning it, and thus to raise and lower the said hook X, as the case may be, and as may be desired, for detaching or attaching the'form from the bed The platen Q isv secured to a yoke, Z, that constitutes thccross-bar to two parallel side pieces, A?, and hung at C, between the frames B, in a suitable positioni'or the platen to be swung 'up and against the form.

These side-pices Az are extended beyond their points oisuspensidn, and between their lower and out'er ends is hung an ope'n box,D2, so as to swing thereon, that, i-n the operation of the press, serves not 'only as a receptaclc forthe cards, &c., printed and thrown o i of the form, todrop or fall intobut as a counterbalanco or weight to the platen. l

E2 is a bar, extended in an upward curve or arc-shape'across the box D2, from o'ne .end'to the other.

On this bar, E, is hung the lower endot` a rod, \F2,`which, at its upper end, G?, made of a fork-shape, and, by such end, is arranged to move over and upon the gear-wheel shaft H. This'rod, F2, en one side, near -its forked end, is provided with a frictionroller, Hthat is properly located to bear uponand against the periphery of the cam-Hange I2, formed upon one side or face of the gear-wheel Gr, hereinbefore referred to.

This cam, I2, is made of such a shape that when the wheel carrying it is revolved, the rods F2, throilgh its friction-roller, will be moved inlthe proper direction to'swing the platen up toward the form, and thus into position for the impression-armsN to takeit, as will be soonfdescribed, and to there leave it, before'the impressionis given, the latter being eected by said arms NI 4 K, a spiral spring, arranged inr a tube or case, L2, upon the inside of one of the frames, B, wherein, at one i end, it is fixed, and at the other, through a rod, MZ, hung to the box D, so that being distended as the platen is swungup, it will, by its contraction, tend to facilitate the swinging o of the platen from the form, (see iig. 5.)

Anotherform of Buch spring is shown in fig. .6, in which a straight spring,'K,. is shown attached to therear lside of th'e bex D? at di, its ends being free. When the platen moves upward, the spring K3, :at eachend, comes in contact with pins oiyprojections, b2, in each side of the frame B. t

The spring is thus bent, and after the platen is released from the arms N, assists in retracting the platen from the bed, in regaining its legitimate shape. l, I The yoke to-which the platen is fixed is extended upon each side, s'o as to form side-arms, N?, thereto, that are notched or recessed similarly upon their upper surfaces, Q2, for the heads of `the extension-arms N of the boxes to` t and drop into, when the platen, as above described, has been brought up nearly to the form.

P2, a Ihorizontal shaft, extended across the framework A, in bearings of which itturns, and provided at each end with an arm, QZ, in proper position to act upon and against the underside of the extensionlarms N,

Vto the boxcsJ, and thus to raise them.

This shaft PL is provided with an4 arm, Q3', between the two sideframcs B, which, arm carries""a frictionroller, R2, that, as the gear-wheel G turns, runs hpon the liange S2, projecting from its'face T2, (see iig. This ange S2 extends around the wheel, and for the greater part of its length is concentric therewith, but made of a cam-shape for the remainder, as seen at U2.V f

This flange operates by its concentric portion to hold the extension-alims N ofthe boxes in a raised position, .and by its cam-portion to so turn 'or rock the yshaft l?2 as to allow the said arms N to drop oufall, and then again to raise them; this falling of the arms N taking place when, by the lmovement'nf the press, the platen 'has been brought up nearly against' the form, and being provided for, then allowingsucli arms to become engaged with the recesses provided'therefor in the arms of the platen-yoke.

The ink-rollers are carriedbetween the arms A, that, by their extension-pieces B3, are fixed to a rockershai't, 03 turning in .suitable bearings of the frames B; and as the arrangement of such rollers upon the arms forms no part of the present invention, I do not deem it necessary to herein further explain it, as it may be of any of the arrangements now in common use, or of one I have invented, and is'her'eafter to be embraced by me in a separate and another application for Letters Patent. p

The rocker-shaft Cfkis` provided with an arm,D3, which, at its outer end, carries a friction-roller, Ea arranged to bear up'on and travel over the eam-iange l"s to the gear-wheel Gr, which 0am is shown in iig. 3, and is so formed as to rock theshaft at the proper time for carrying tho ink-rollers over the form. v

Gi, a lever-arm, provided with a rest, H3, by means of which the arm D3 tothe shaft can be held oli' from tho cam-flange F3, and the inlcrollers in contact with the idk-cylinder L3 for ldistributing the-ink thereon, Ste.

The operation `of the several parts to the press, constructed and arranged as above'described, is as follows:

`The {1y-wheel D is turned iu the direction represented by the red arrows in :the drawings, which, through the connecting parts, with the platen, causesy the platen to be swung up nearly to the form, where, leaving it, the arms N then engage therewith, and by the` horizontal movement thus imparted to the boxes il, through the action of the arms H, upon the inside of the same, such platenl is made to move up against the form, thereby taking an impression therefrom, when, the revolution oi' the ily-'wheel continung,'thearms N are disengaged from the platen which .then falls or swings off from the form into position for being again carried up thereto as before, andso on as Along as the machine' is run.

`to all experienced in the running printing-machines.

The disengagement of the impression-arms N from the platen is effected 'through the rocker-arms Q2, that raise theni inthe propcrtirne therefor.

From the platen the cards, &c., printed, fall down' into the box D2, which box, as it'is suspended to the frame carrying the platen serves as a counterwoight orb'alance therefor.

BP, `a hook-lever, hung to one ofthe side-frames B, in position for its hook-end to engage with thepin j in the rocker-'arm Q2, and thus enable it to be swung into a position suitable for so holding the impression-arms N that they cannot connect With'tho platen as the maohin'c is running, the convenience of which lever is obvious Having thus described my invention, I claim as new; and desire to secure Letters Patent- 1. The arm or arms N, or its or their equivalents, in combination with the platen Q, or its equivalent, when arranged to engage with the said platenf and to draw it against the form to which it has been previously raised, substantially as and for the purpose described.

2. The rocker-arm or arms Q?,cr its or their equivalents, arranged for operation upon the arm or arms N, or equivalent therefor, substantially as described for the purpose specified.

3. The lever or levers M3, or equivalent therefor, when'arranged for operation upon the rocker-arm or arms Qz of the lifting-device to the impression-arms N, substantially as and for the purpose described.

` 4. A movable hook or clasp for holding the chase to the bod of thefpress, when operated by lover d?, and arranged foroperation substantially as specified. l

v5. The lever G'orits equivalen-t, in combination .with the frame carrying the ink-ro1lers to the press, when' arranged for operation therewith, substantially as and for the purpose described.

6. A box or receptacle, in combination with the frame carrying the platen, when arranged thereon for operation, substantially as and for the purpose set forth, v
